I made a mistake in programing an ATtiny for an electronic embroidery circuit and had to use alligator clips to reprogram the microcontroller while it was already sewn into the eTextile Breadboard.
Set up the Arduino Uno as ISP.
Attach alligator clips to the male to male jumper cables.
Carefully attach the alligator clips to the ATtiny pins and upload the program.
sweet success!
